Sony VAIO VPCYB25AG/B is 11" netbook. Bought it for~ Rs22K. It was very useful for my travel abroad as I wanted to access net and also to download my photos on to it.
It comes with 320gB hard disc and with the following specs AMD Dual-Core Processor E-350 with AMD Radeon™ HD 6310 Discrete-Class Graphics Windows® 7 Starter 32-bit 11.6(29.5 cm) wide(WXGA: 1366x768) TFT colour display(VAIO Display, LED backlight) In summary it is very light weight at 1.5kg(including the 130g charger) 4 hr battery.
On the bad side, it is slow for anything other than internet, be it installing new software, copying from SD card, opening office documents etc.
If your application is just internet related, then it is quite OK.
It has no optical drive(ie no CD/DVD).
Has a couple of USB ports.
The camera provided is good for nothing.
Overall I loved this laptop, it is great for travel. Buy it if that is the main purpose.
